- Survey operations
- A research or survey vessel is mapping the seabed or water column, often while towing equipment.
- Until further notice
- The operation or danger has no scheduled end; the warning stays in force until a later message cancels it.
- Area bound by
- Introduces a list of positions that are the corners of an area — the polygon the warning applies to.
